INSTALLATION INSTRUCTIONS

L2556 07/06

GENERAL

The manufacturer assumes no re-

sponsibility for equipment installed

in violation of any code require-

ment.

These instructions give information

relative to the installation of these

enclosures only. For other related

equipment refer to the proper in-

structions.

Material in this shipment has been

inspected at the factory and released

to the transportation agency in good

condition. When received, a visual

inspection of all cartons should be

made immediately. Any evidence

of rough handling or apparent dam-

age should be noted on the delivery

receipt and the material inspected

in the presence of the carrier’s

representative. If damage is found,

a claim should be ﬁ led against the

carrier immediately.

ENCLOSURE MOUNTING

The installer must adhere strictly to

all local and national code require-

ments pertaining to the installation of

this equipment. These enclosures

are designed to be installed in the

ceiling for horizontal mounting only.

Location of the unit must be in an

area providing adequate access to

the ceiling panel since all compo-

nents must be serviced from this

area.

The enclosure should be lifted to

the desired location and secured

using the mounting holes located on

the top with an acceptable mounting

method (Figure 1). The enclosure

must be level in both directions to

permit proper drainage of the fan

coil.

After the enclosure is mounted a

2x2 or 2x4 frame must be installed

around the base of the enclosure

to create an air tight seal. Figure 7

shows a typical arrangement for the

framing required.

**WARNING TO INSTALLER, SERVICE PERSONNEL AND OWNER**

Altering the product or replacing parts with non authorized factory parts voids all warranty or implied war-

ranty and may result in adverse operational performance and/or a possible hazardous safety condition to

service personnel and occupants. Company employees and/or contractors are not authorized to waive this

warning. Current Maintenance Program is available at www.ﬁ rstco.com under “Product Information”.

****** WARNING ******

Extreme caution must be

taken that no internal damage

will result if screws or holes

are drilled into the cabinet.

INSTALLING FAN COIL

UNIT INTO ENCLOSURE

1. Ensure that the enclosure has

been installed level.

2. Remove motor/blower assembly

from the fan coil.

3. Lift coil assembly into enclosure

and place the top ﬂ ange of the coil

onto the top surface of the mount-

ing angles at each end of the en-

closure.

4. Slide coil assembly forward until

the supply duct ﬂ anges of the fan

coil are fully engaged into the front

of the enclosure.

NOTE: Before fastening, the fan

coil unit must be fully engaged

into the supply duct ﬂ ange. If not,

supply air may recirculate into

the enclosure. To ensure total

engagement, push the fan coil

unit forward. Total engagement

has occurred when the front of

the top plate and the front of the

drain pan are squeezing against

the insulation.

5. Fasten the coil assembly to the

fan coil with sheetmetal screws

through the slots in the mounting

angle.

6. Install motor/blower assembly.

7. Check to make sure that the fan

coil is level and that the drain pan

will drain properly.

certain that the fan coil unit is

secured ﬁ rmly to the enclosure

with sheetmetal screws through

the mounting angle.

Refer to enclosure mounting in-

structions on page one.

CONNECTION OF AIR

DISTRIBUTION DUCTS

All duct work must be installed

in accordance with National Fire

Protection Association Codes 90A

and 90B. Since the return air to the

unit is through louvers in the ceiling

panel, applicable installation codes

may limit the unit to installation only

in single story residences.

The enclosure has supply duct

ﬂ anges to accommodate the con-

nection of a supply plenum, how-

ever extreme care must be taken to

insure proper fastening of the supply

plenum to the enclosure.

The fastening of the supply plenum

edge it will not permit the fan coil to

engage completely. (2) If the enclo-

sure and fan coil unit are mounted as

an assembly and the duct fasteners

are too close to the front edge they

may also secure the ﬂ anges on the

fan coil unit preventing the removal

of the unit from the enclosure.

An optional return air cutout is sup-

plied on the rear of the enclosure to

permit ducted return and is shown in

Figure 6. Rear entry ducted return

requires the use of a solid ceiling

panel.

ENTRY POINT

CONNECTIONS

For general reference the following

items are shown in Figure 6:

-optional return air plenum cutout

-entry points for connection to re-

frigerant lines, water coil, electrical

lines, and drain lines.

Refer to individual fan coil instal-

lation instruction for speciﬁ c piping

and electrical wiring requirements.

****** WARNING ******

It is recommended that the

enclosure and fan coil be

protected (covered) during

the dry wall and painting pro-

cess to prevent the spraying

of the material into the enclo-

sure and on the fan coil.

****** WARNING ******

The fan coil unit protrudes

approximately 1-1/2 inches

into the supply duct ﬂ anges

on the enclosure. (Figure 5)

****** WARNING ******

The fasteners securing the

duct must be at least 1-3/4

inches away from the front

edge of the enclosure.

ENCLOSURE WITH FAN

COIL FACTORY MOUNT-

On larger units, installation may be

easier if the enclosure and unit are

mounted separately. Unit removal

is the reverse of the installation pro-

cedure above.

NOTE: Before mounting the en-

closure check to see if the fan

coil unit is fully engaged into the

supply duct ﬂ ange. Total engage-

ment is when the front of the top

plate and the front of the drain

pan are squeezing against the

insulation. Also check to make

must be at least 1-3/4 inches away

from the front edge of the enclosure.

This prevents two problems: (1) If

the enclosure is mounted without

the fan coil installed and the duct

fasteners are too close to the front
